To all when/b it may concern.-

Be it known that we, BRUCE BENNETT and JOHN E. MOORE, citizens of the United States, residing at New Haven, in the county of Gallatin and State of Illinois, have invented certain new and useful Improvements in Clod- Crushers; and We do declare the following to be afull, clear, and exact description of the invention, such as will enable'others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the rletters of refer.

ence marked thereon, which form a part of this specification.

This invention relates primarily toimprovements in @lod-Crushers, land-rollers, and the like; but, as will be apparent from the description hereinafter, it is likewise applicable to many other classes of machinery.

The primary object of the invention is to provide a c rusher so mounted uponsuitable conveying apparatus`that it may be readily raised and lowered into and out of conta'c't with the ground and a ineansf'or suspending the crush-er inV elevated position and for forcing the same into operative position.

The invention also contemplates the provision of aframework capable of being raised and lowered with the crusher and a provision for keeping said framework in substantially -a horizontal plane, so that its main weight will be borne by the main axle of the machine.

The invention also contemplates a suitable connection and operating` means between the tongue or draft-pole of the machine and the framework, whereby the weight of the frame-' work may at all times be supported by a part of the machine other than the tongue.

In the accompanying drawings an embodiment of the invention is illustrated, and in hereinafter referring to the same like letters of reference refer to `corresponding parts in the several figures.

Figure 1 is a side elevational View of the machine, parts being broken away for clearness of illustration. Fig. 2 is a corresponding view, the elements of the machine occupying a different position from that shown in Fig. l. Fig.l 3 is a plan view of the crusher and its associated parts. Fig. 4 is a detail View of the axle of the machine and the gears secu red thereto. Fig. 5 is a perspective View ,its respective ends..

ofthe lever for lowering the forward portion of the framework, showing itsmanner of attachment to the tongue; and Figs. 6, 7, 8, and

therewith is an operating-pinion D, carried' 7o by the axle d of the crusher E. The crusher may be of any usual or preferred construct-ion, but,as shown in Fig. 3,1't preferably comranged alternately thereon. The axle d of the'crusher is supported in a portion of a framework F, which carries the whole of the crusher apparatus, andis'arranged to be elevated and lowered with the crusherin a man- 8o ner to be described. Clutches e2 are so arranged With relation to the operating-pinions of the crusher vthat when the crusher is elevated and the machine backed for any reason the pinions will'be freeto rotate without 85 rotating the crusher, while the forward motion of the machine impartsa constant rotary motion to the crusher. About midway its longitudinal length the framework F carries toothed segments G, adapted to be en- 9o gaged by pinions G', keyed to the shaft B at These segments are held in constant mesh with their pinions by means of the apertured guide-plates H, also carried by the framework and adapted to'work over 95 the axle B: y

At a con venient point on the axle Bis keyed a gear J of convenient size, and this gear is adapted to be turned by a worm 'J', formed on a substantially vertically disposed shaft roo J2, passing upwardly through the framework F andcapable of 'a slight pivotal "movement therein through the medium of a ball connection j, Fig. 9. This rod is designed to be the conveying or traction 6o vThe wheels are free to tu rn ,fm and releasing-grip m.

tuined by a hand-wheel JS or other suitable operating means located near the seat J", secured at to the framework. From so much of the description it will be apparent that, by reason of its operaiingpinions being in constant engagement". with the circular racks on the respective wheels, when it is desired to raise or lower the crusber the operator merely turns the hand-wheel Ji, and through the medium of the shaft J2, worm J', and gear J imparts a rotary movement. to the pinions G',op erating on the racks G, whereupon thel racks will be carried upwardly or downwardly, as the case may be, and by reason of their cnrvature in relation to the curvature of the circular racks the crusher will consequently be correspondingly raised or lowered, the former position being` clearly shown in Fig. l and t-he latter in Fig. 2.

Some mechanism must be employed for maintaining a proper position of the framework and for relieving the tongue or draftpole from all strain whatever incident to the weight of the framework and Crusher, and this feature may now be described.

Extending forwardly from the guides II are rods K, rigidly secured to the framework and properly connected at their forward ends. To these rods at the point 7c is pivoted a tongue or draft-pole L, and upon the draftpole in suitable brackets l is pivoted a lever M, provided with the usual pawl and ratchet The extended portion N of this lever is pivoted at itsouter end to an inverted- U-shaped bracket or support O, working over the tongue L and rigidly secured to the beam P,/c, aiecti"ng-tl16 QXYSald ions ofthe nTd's'K. tion it will be seen that when the Crusher is in elevated position the lever M will be drawn backward and the parts will occupy the position shown in Fig. 1, while, on the other hand, when the frame is lowered the lever will then be thrown forward andthe parts will occupy the positions shown in Fig. 2, with the framework still in substantially horizontal position and the weight of the apparatus still supported by the main axle of the machine. By this arrangement it will be seen that the tongue, by reason of its pivotal connection, may always occupy a proper relative position to an animal drawing the machine, irrespective of the position of the crusher and its framework, and also that any strain incident to the weight of the crusher and the framework will be borne by the axle of the machine and its tractionwheels, rather than, as is usually the case, be imparted to a greateror less extent to the tongue of the machine.

To protect the gear J and its operatingworm J' from dirt and the like, it is preferably confined within a two-part casing Q, Vbolted together at q, and the clutches e2 are correspondingly proteced by casings Q', bolted together at q.

From this construc- Itis to be understood that whenever the word crusher appears herein it is used for the purpose of affording a clear description of one application of the combination set forth in the claimsand that such term is to be considered broad enough to cover not only clod-crushers, but also the various styles of pnlverizers and other agricultural implements in connection with which the combination may be as readily used.

Having thus described the inven tion, what is claimed as new, and desired to be secured by Letters Patent, is-

l. In a machine of the character described the combination with supporting and'conveying wheels, of circular racks on said wheels, a crusher, pinions on the Crusher for engaging the racks on the wheels, a framework supporting the crusher, racks on the framework, pinions in -elngfagement with the racks on the framework, and means for 0perating said lastmentioned pinions for causing the racks to be raised and lowered and the crusher correspondingly operated, substantially as described.

2. In a machine of the character described, the combination with suitable supporting and conveying wheels, of a framework and Crusher, means for raising and lowering the framework and Crusher, and means for maintaining the framework iu horizontal position comprising a tongue or rod pivoted thereto, and means operating substantially as described, to shift the rod and framework relative to each other.

In a machine of the character described, the combination with suitable su pporting and cenzeying wheels, ot' toothed racks on said wheels, a'crnsherinmesh with the toothed racks of the \vheels,`a"'inovable framework supporting the crusher, racks carried bythe framework and guided by the axle of the machine, pinions in engagement with said racks, and means for yoperating said last pinions to raise and lower the framework and crusher comprising an operating-lever, a worm on the lever and a gear on the axle of the machine, substantially as described.

4. In a machine of the character described, the combination with suitable supporting and conveying wheels, of a crusher, a movable supporting-framework for the crusher, means for raising and lowering the framework and crusher, a tongue pivoted to said framework, and means carried by the tongue for raising and lowering the forward portion ofthe framework to maintain the horizontal position of the framework, substantially as described.

5. In a machine of the character described, the combination with suitable supporting and conveying wheels, of a crusher, a movable support for said crusher, means for raising and lowering the support and crusher, a tongue pivoted to the support, and means on the tongue for maintaining the support in proper horizontal position, comprising a suit- IOO and-pinion mechanism, an operating-rod for the worm, and a universal connection between the rod and the framework adapted to operate substantially as described.

In testimony whereof We affix our signatures in presence of two Witnesses.v
